This is file footage of the first test drive of the new Office Chairiot Mark II motorized IKEA chair in the lab/workshop at StuffAndyMakes.com HQ:
The motors were smaller (100 WATTs) and the joystick was not enclosed in anything (I was holding it with the wires out in the open and everything). At the time, the drive wheels were in the front of the chassis. They will be put in the rear for stability at speed.
